Cap and Tear Ring for Wax-Coated Beverage Bottle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The removal of a wax coating from beverage bottles is often difficult, interfering with opening and dispensing the beverage, as the wax can adhere tenaciously to the bottle and stopper, potentially entraining wax pieces in the beverage.
Innovation Solution
A cap assembly with a spike to pierce the stopper, a tear ring with mechanical weakening for easy separation, and a pull tab for manual grasping, allowing the cap to be removed along with the wax coating, thereby facilitating the removal of the wax coating from the bottle mouth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wax coating is applied to the bottle and stopper for sealing and aesthetic purposes, then the bottle is well-sealed and visually appealing, but the wax adheres tenaciously making removal difficult and interfering with opening and dispensing
Solution Approach 1:
The cap assembly is divided into separable components: a cap portion that remains on the bottle and a tear ring with pull tab that can be easily removed. This segmentation allows the wax coating to be effectively removed along with the tear ring portion, resolving the contradiction between maintaining reliable sealing and enabling easy removal.
Solution Approach 2:
The tear ring acts as an intermediary element between the cap and the bottle. It provides a removable component that facilitates wax removal while the cap portion maintains the sealing function. The tear ring with its pull tab serves as a mediator that enables easy separation without compromising the overall sealing effectiveness.
2Reliability
If the wax coating is made thicker for better sealing and protection, then the sealing and protective function is improved, but the wax becomes more difficult to remove and may entrain wax pieces in the beverage
Solution Approach 1:
By segmenting the cap into a stationary cap portion and a removable tear ring portion, the design allows selective removal of the tear ring with its attached wax coating. This prevents thick wax coatings from being removed as single large pieces that could contaminate the beverage, while still maintaining effective sealing during storage.
Solution Approach 2:
The tear ring with pull tab is designed to be extracted or removed from the cap assembly. This extraction mechanism allows the wax coating on the removable portion to be cleanly taken off the bottle, preventing wax pieces from remaining on the bottle mouth and potentially entering the beverage during dispensing.
3Ease of operation
If a removable cap assembly is used to facilitate wax removal, then ease of operation is improved, but the device complexity increases with additional components like spike, tear ring, and pull tab
Solution Approach 1:
Multiple functions are merged into a single integrated cap assembly: the spike for piercing the stopper, the cap portion for sealing, the tear ring for wax removal, and the pull tab for easy manipulation. This merging reduces the need for separate tools or complex multi-step processes, simplifying the overall operation despite the integrated structure.
Solution Approach 2:
The cap assembly is designed as a multi-functional unit that performs multiple operations: sealing the bottle, piercing the stopper for retention, facilitating wax coating application, and enabling easy wax removal. This universal design consolidates what would otherwise require multiple separate components or steps, managing complexity through functional integration.

AI summary
An apparatus and method for coating an end of a stoppered beverage bottle in wax are provided. A cap assembly is positioned over a mouth of the bottle prior to coating the end of the bottle in wax. The cap assembly may facilitate removal of a portion of the wax from the bottle to allow removal of the stopper and dispensing of the beverage. In an implementation, the cap assembly includes a cap portion sized to be received over at least a portion of a bottle mouth and the stopper. A spike protrudes downwardly from the cap portion, and is configured to at least partially pierce a bottle stopper. A tear ring is frangibly attached to the cap portion by one or more regions of mechanical weakening. A pull tab extends outwardly from the tear ring to facilitate frangible separation of the tear ring from the cap portion.
